Danas \u0107emo razgovarati o jo\u0161 jednom bleydu Check Point \u2014 <b>Svest o identitetu<\/b>. Ve\u0107 na samom po\u010detku, kada smo opisivali NGFW, definirali smo da je neophodna mogu\u0107nost regulisanja pristupa na osnovu korisni\u010dkih naloga, a ne IP adresa. To se pre svega odnosi na pove\u0107anu mobilnost korisnika i sveprisutnu primenu modela BYOD \u2014 donesi svoj ure\u0111aj. U firmi mo\u017ee biti vi\u0161e ljudi koji se povezuju putem WiFi-a, dobijaju dinami\u010dke IP adrese i to iz razli\u010ditih mre\u017enih segmenata. Poku\u0161ajte ovde da kreirate pristupne liste na osnovu IP adresa. Ovdje je identifikacija korisnika neophodna.
